Key Concepts in Mathematics

Arithmetic
- Fundamental operations include addition, subtraction, multiplication, and division essential for calculations.
- Properties include commutative (changing order does not change sum/product), associative (changing grouping does not change sum/product), and distributive laws (multiplying a number by a sum results in the same sum as multiplying each addend separately).
Algebra
- Composed of variables (symbols representing numbers) and constants (fixed values).
- Involves expressions (combinations of variables and constants), equations (statements of equality), and inequalities (comparisons showing one side is larger/smaller).
- Functions include linear (straight lines), quadratic (parabolas), polynomial (multiple terms), and exponential (growth/decay rates).
- Techniques for solving linear equations and systems are critical for finding unknown values.
Geometry
- Fundamental shapes include triangles, circles, squares, and rectangles with distinct attributes.
- Important measurements include perimeter (distance around a shape), area (space within a shape), and volume (space within 3D shapes).
- Key theorems include the Pythagorean theorem (relationship between sides of a right triangle) and properties of angles (rules governing angle relationships).
- Coordinate geometry involves formulas for calculating distance, midpoint, and slope between points on a plane.
Trigonometry
- Core trigonometric ratios are sine, cosine, and tangent, essential for understanding triangle properties.
- Right triangles exhibit consistent relationships between angles and side lengths.
- The unit circle aids in defining trigonometric functions and understanding periodic behavior.
Calculus
- Limits help analyze what happens to a function's output as the input approaches a specific value.
- Derivatives measure how a function changes, representing the slope or rate of change at a point.
- Integrals calculate the area under a curve, representing the total accumulation of quantity.
Statistics
- Descriptive statistics summarize data with measures like mean (average), median (middle value), mode (most frequent value), and range (difference between highest and lowest).
- Probability principles address how likely events are, differentiating between independent (unrelated outcomes) and dependent events (outcomes influence each other).
- Common distributions include the normal distribution (bell curve) and binomial distribution (success/failure scenarios), with standard deviation indicating data spread.
Discrete Mathematics
- Set theory covers operations involving sets, such as union, intersection, and uses Venn diagrams to visualize relationships.
- Graph theory examines networks through vertices (points) and edges (connections), exploring paths and circuits within structures.
- Combinatorics analyzes arrangements and selections, focusing on permutations (order matters) and combinations (order doesn't matter).
Mathematical Logic
- Propositions are assertions that can be classified as true or false.
- Logical operators include AND, OR, and NOT, used for constructing compound statements.
- Proof techniques such as direct (showing truth), contrapositive (proving opposite), and contradiction (demonstrating impossibility) are foundational for establishing validity in arguments.
